Documentation

The expression value calculation is implemented using IronPython, which explains the following features:

  • The expression is not limited to one mathematical operation 2+3*4*(5+6*7)-sqrt(2)
  • If at least one operand is a real number, the result of the expression will be real 2/3=0 and 2./3=0.666666666667
  • Special variable _ - stores the result of the last calculation
  • The implementation of mathematical functions is in the calc.py file and can be supplemented or changed as needed.
